Problems solved by technology

Existing electric new energy buses generally use double bridges, the front axle is used as the steering axle, and the rear axle is used as the driving axle. When the rear axle of the new energy bus adopts the centralized drive mode, the structure of the drive system is limited. When the inner floor of the car is low-floor, the position of the inner floor of the car corresponding to the drive axle and tires is higher, and the seats installed in these positions are higher. , it is not convenient for the occupant to get up and sit down

Embodiment 1

[0023] Such as figure 1 As shown, a four-axle single-tire electric bus includes a chassis 1, a steering mechanism 2 and a driving mechanism 3, wherein the steering mechanism 2 and the driving mechanism 3 are fixed on the chassis 1, and the steering mechanism 2 is located on the driving mechanism 3 front side. The steering mechanism 2 of the present embodiment includes a first steering axle 201 and a second steering axle 202, the first steering axle 201 and the second steering axle 202 are arranged laterally and parallel to each other, and the first steering axle 201 and the second steering axle 202 are horizontal The heights are the same and there is a certain distance in the longitudinal direction. Both sides of the first steering axle 201 and the second steering axle 202 are provided with steering wheels 207 . The drive mechanism 3 of the present embodiment includes a drive axle, an electric drive system and a drive wheel 303, wherein the drive axle includes a first drive a...

Embodiment 2

[0026] Such as figure 2 As shown, this embodiment makes the following further limitations on the basis of Embodiment 1: the steering mechanism 2 of this embodiment also includes a longitudinal tie rod 203, a steering booster 205 and an intermediate tie rod 206, wherein the first steering axle 201 and The second steering bridge 202 is connected with a steering rocker arm 204, and the trailing rod 203 and the intermediate tie rod 6 are arranged longitudinally and coaxially. Both ends of the arm 204 and the middle tie rod 206 are respectively connected to the steering rocker arm 204 on the first steering axle 201 and the steering rocker arm 204 on the second steering axle 202 .

[0027] When this embodiment is applied, the steering booster 205 drives the longitudinal tie rod 203 to move, the longitudinal tie rod 203 transmits power to the steering rocker arm 204 on the first steering axle 201, and the steering rocker arm 204 on the first steering axle 201 drives the intermediate...

Embodiment 3

[0029]This embodiment makes the following further limitations on the basis of Embodiment 2: the steering rocker arm 204 of this embodiment includes a horizontally arranged transverse connecting plate and a longitudinally arranged longitudinal connecting plate, wherein the front end of the longitudinal connecting plate and the transverse connecting plate Connection, the longitudinal connecting plate is connected with the transverse connecting plate to form an "L" shape as a whole. In order to increase the structural strength of the steering rocker arm 204, the transverse connection plate and the longitudinal connection plate of the steering rocker arm 204 are integrated into one body in this embodiment. In this embodiment, the steering rocker arm 204 on the first steering bridge 201 is arranged on the first steering bridge 201 through the limit pin passing through the connecting portion of the transverse connecting plate and the longitudinal connecting plate, and the steering ro...

Abstract

The invention discloses a four-axel single-tire bearing electric bus which comprises a chassis, a steering mechanism and a driving mechanism. The steering mechanism and the driving mechanism are fixed to the chassis, the steering mechanism comprises a first steering axle and a second steering axle, the first steering axle and the second steering axle are both transversely arranged and are parallel, and steering wheels are arranged on the two sides of the first steering axle and the two sides of the second steering axle respectively. The driving mechanism comprises driving axles, electric driving systems and driving wheels, the driving axles comprise the first driving axle and the second driving axle, the first driving axle and the second driving axle are both transversely arranged and are parallel, and the driving wheels and the electric driving systems enabling the driving wheels to rotate are arranged on the left side and the right side of the first driving axle and the left side and the right side of the second driving axle respectively. When the electric bus is applied, the steering wheels, the driving wheels and the electric driving systems small in size can be adopted, the height difference between compartment floor protrusions and a compartment floor can be reduced, the compartment floor protrusions correspond to the mounting positions of the steering wheels, the driving wheels and the electric driving systems, and after seats are arranged on the protrusions, passengers can sit down and stand up conveniently.

Description

technical field [0001] The invention relates to a bus, in particular to an electric bus carried by a single tire on four bridges. Background technique [0002] In recent years, people have paid more and more attention to energy conservation and environmental protection. Electric new energy buses such as pure battery electric buses, hybrid buses, extended-range buses, dual-source trackless electric buses, and trackless electric buses have energy-saving features. The advantages of emission reduction and the rapid development. Existing electric new energy buses generally use double bridges, the front axle is used as the steering axle, and the rear axle is used as the driving axle. When the rear axle of the new energy bus adopts the centralized drive mode, the structure of the drive system is limited. When the inner floor of the car is low-floor, the position of the inner floor of the car corresponding to the drive axle and tires is higher, and the seats installed in these posi...
