Problems solved by technology

Existing electric new energy buses generally adopt a single front axle steering scheme, and the tire load is large. In order to meet the load-carrying requirements, larger tires need to be used. The seat arrangement at the inner steer tire is high, which is not convenient for occupants to sit and get up

Embodiment 1

[0013] Such as figure 1 As shown, the double-bridge steering mechanism of an electric bus includes a first steering axle 1, a second steering axle 2, a longitudinal tie rod 3, a steering booster 5, and an intermediate tie rod 6, wherein the first steering axle 1 and the second steering axle 2 are arranged horizontally and parallel to each other, and both the first steering bridge 1 and the second steering bridge 2 are connected with a steering rocker arm 4. The longitudinal tie rod 3 and the intermediate tie rod 6 are arranged longitudinally and coaxially. The two ends of the longitudinal tie rod 3 are respectively connected to the steering booster 5 and the steering rocker arm 4 on the first steering axle 1, and the two ends of the intermediate tie rod 6 are respectively connected to the first steering axle The steering rocker arm 4 on 1 and the steering rocker arm 4 on the second steering axle 2. In this embodiment, a steering wheel 7 connected to the first steering bridge 1...

Embodiment 2

[0016] This embodiment further defines the following on the basis of embodiment 1: The steering rocker arm 4 of this embodiment includes a horizontal connecting plate and a longitudinal connecting plate, wherein the front end of the longitudinal connecting plate and the transverse connecting plate After connecting, the longitudinal connecting plate and the horizontal connecting plate form an "L" shape as a whole. In order to provide the structural strength of the steering rocker arm 4, in this embodiment, the horizontal connecting plate and the longitudinal connecting plate of the steering rocker arm 4 are integrated into one body. In this embodiment, the steering rocker arm 4 on the first steering bridge 1 is set on the first steering bridge 1 by a limit pin that passes through the connecting part of the transverse connecting plate and the longitudinal connecting plate, and the steering rocker arm on the second steering bridge 2 is 4 is set on the second steering bridge 2 by a...

Abstract

The invention discloses a double-axle steering mechanism of an electric bus. The mechanism comprises a first steering axle (1), a second steering axle (2), a longitudinal pull rod (3), a steering booster (5) and a middle pull rod (6). The first steering axle (1) and the second steering axle (2) are transversely arranged in parallel and are respectively connected with a steering rocker (4). The longitudinal pull rod (3) and the middle pull rod (6) are longitudinally and coaxially arranged, the two ends of the longitudinal pull rod (3) are connected with the steering booster (5) and the steering rocker (4) on the first steering axle (2) respectively, and the two ends of the middle pull rod (6) are connected with the steering rocker (4) on the first steering axle (1) and the steering rocker (4) on the second steering axle (2) respectively. When the double-axle steering mechanism is applied to electric new energy busses, influences on distribution of seats in a compartment can be reduced, the seats can be reasonably distributed in the compartment conveniently, and passengers can sit down and stand up conveniently.

Description

Technical field [0001] The invention relates to an electric bus, in particular to a double-bridge steering mechanism of the electric bus. Background technique [0002] In recent years, energy conservation and environmental protection have received more and more attention. Pure battery electric buses, hybrid buses, extended-range buses, dual-source trackless electric buses, trackless electric buses and other electric new energy buses have energy-saving features. The advantages of emission reduction have developed rapidly. Existing electric new energy buses generally adopt a single-front axle steering scheme. The tire load is large. In order to meet the load demand, larger tires are required. This results in a higher height of the inner floor of the steering tire installation position. The seat layout at the inner steering tire is relatively high, which makes it difficult for the occupants to sit and get up. Summary of the invention [0003] The purpose of the present invention is...
