Problems solved by technology

[0006] In the current rack and rack transmission technology, it is through the way of gear and rack, or the way of worm and rack. In the above two ways, the thrust is generated by sliding friction, which causes serious wear and tear on the rack, and the transmission efficiency is not good. High, there is an urgent need to develop a new type of high climbing performance gear and rack combination structure for rail transit to solve the above problems

Abstract

The invention discloses a gear and rack combined structure having high gradeability and for rail traffic. While a vehicle runs on an H-shaped beam, walking wheels contact the top of the H-shaped beam to provide a support for the vehicle, balancing wheels clamp the left side and the right side of the vehicle on a combined beam, and derail is prevented during running; while the vehicle climbs a road having a large slope, power is provided by transmission of racks of the H-shaped beam and worms of the vehicle, the gradeability of the vehicle is improved, the theoretical gradeability can reach 90 degrees, and the problem that the gradeability is poor in rail traffic can be solved. The special rack structure can change slide friction into rolling friction of a push bearing, abrasion is reduced, the transmission efficiency is improved, and the gear and rack combined structure has promotion and use value.

Description

technical field [0001] The invention belongs to the technical field of special packaging, and in particular relates to a gear and rack combination structure with high gradeability for rail traffic. Background technique [0002] Existing rail transit technologies are mainly subways and light rails. The subway is through the contact between the wheel set tread and the track, and the friction force between the wheel set and the rail drives the subway vehicle to travel. The light rail is in contact with the reinforced concrete track through the rubber tire, and the light rail vehicle is driven by the friction between the rubber wheel and the concrete track. [0003] In the current rack and rack transmission technology, it is through the way of gear and rack, or the way of worm and rack. In the above two ways, the thrust is generated by sliding friction, which causes serious wear and tear on the rack, and the transmission efficiency is not good. high. [0004] The disadvantage...
