This type of high-deflection wheel was developed for routes with very specific challenges \u2013 for rail lines in historic city centres with protected buildings or carriage concepts without a primary shock absorber stage where element-sprung wheels are physically limited. The BVV double-ring shock absorber with integrated safety shoulders has proven itself worldwide \u2013 in terms of comfort as well as safety aspects.[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” scene_position=”center” text_color=”dark” text_align=”left” overlay_strength=”0.3″ shape_divider_position=”bottom” shape_type=””][vc_column column_padding=”no-extra-padding” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” column_border_radius=”none” width=”1\/6″ tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid” offset=”vc_col-lg-2 vc_col-md-3 vc_hidden-sm vc_hidden-xs”][fancy_box box_style=”color_box_basic” icon_family=”none” box_color=”#3c6a81″ box_color_opacity=”1″ box_alignment=”left” min_height=”50″]\n

Maintenance-free rubber elements and easy, quick tyre change High radial spring deflection combined with high axial stiffness: This means that LoRa also meets exceptional requirements for reducing impact, body-conducted noise and airborne noise as well as track guidance requirements in the most difficult railway networks. It has been specially developed for high axle loads and small diameter running tread, typical of modern low-floor trams with their space-saving design. The 3 mm spring deflection in the static state achieves up to 15 times the deflection of the shock absorber element compared to conventional resilient wheels for well-developed rail lines \u2013 sufficient reserves even under the most difficult circumstances.[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” scene_position=”center” text_color=”dark” text_align=”left” overlay_strength=”0.3″ shape_divider_position=”bottom” shape_type=””][vc_column column_padding=”no-extra-padding” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” column_border_radius=”none” width=”1\/2″ tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid”][vc_column_text]The comfort wheel: TDAN<\/strong><\/p>\n TDAN (Two Discs Ascent \u2013 Noiseless) is a special development for city and tramcars with high axle loads and limited installation space and meets the highest requirements for impact, body-conducted noise and noise reduction. Compared to the LoRa wheel type, the space requirement for the rubber spring mounting in the radial direction is further reduced. Another special characteristic is the very high radial spring deflection with simultaneous track gauge stability. As a result of bearings integrated into the wheel hubs, this type of wheel is preferred when there are high comfort requirements and severely limited clearance in the chassis.<\/p>\n Please don\u2019t hesitate to contact us with your specific requirements!<\/strong>[\/vc_column_text][\/vc_column][vc_column column_padding=”no-extra-padding” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” column_border_radius=”none” width=”1\/2″ tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid”][image_with_animation image_url=”3773″ alignment=”” animation=”Fade In” img_link_large=”yes” border_radius=”none” box_shadow=”none” max_width=”100%”][\/vc_column][\/vc_row][vc_row type=”full_width_background” full_screen_row_position=”middle” bg_image=”3003″ bg_position=”center center” bg_repeat=”no-repeat” parallax_bg=”true” parallax_bg_speed=”slow” scene_position=”center” text_color=”light” text_align=”left” overlay_strength=”0.3″ shape_divider_position=”bottom” shape_type=””][vc_column column_padding=”no-extra-padding” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” column_border_radius=”none” width=”1\/1″ tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid”][divider line_type=”No Line” custom_height=”60″][nectar_animated_title heading_tag=”h2″ style=”color-strip-reveal” color=”Accent-Color” text=”How can we construct your wheel?”][vc_column_text]Each track and carriage format poses different challenges to wheels and wheelsets.
