Embodiment Construction

[0019] In order to better understand the present invention, the embodiments of the invention will be described in detail below in conjunction with the accompanying drawings.

[0020] Please refer to image 3 and Figure 4 , The preferred embodiment of the present invention provides a vehicle, which includes a frame, a box fixed on the frame, a front axle, a rear axle, and a hydropneumatic suspension (not shown) connected to the frame and the rear axle. The rear axle is provided with upper and lower rods; the front axle is provided with longitudinal tie rods and transverse tie rods.

[0021] The vehicle frame includes a left longitudinal beam 2 , a right longitudinal beam 4 arranged opposite to the left longitudinal beam 2 , a plurality of crossbeams 6 and balance beams 8 fixedly connecting the left longitudinal beam 2 and the right longitudinal beam 4 . Both the left longitudinal beam 2 and the right longitudinal beam 4 include a front end 21 facing the same direction as the...

Abstract

The invention provides a frame and a vehicle with the frame. The frame comprises a left longitudinal beam, a right longitudinal beam, a balance beam, transverse beams, rear pull rod supports, front suspension cylinder supports, longitudinal pull rod supports and a transverse pull rod support. The balance beam is fixedly installed at the middle rear parts of the left longitudinal beam and the right longitudinal beam. The two ends of the balance beam penetrate out of the webs of the left longitudinal beam and the right longitudinal beam and are exposed out of the left longitudinal beam and the right longitudinal beam. The rear pull rod supports are respectively and fixedly installed on the left longitudinal beam and the right longitudinal beam and are arranged below the balance beam. At least one transverse beam is fixedly installed between the left longitudinal beam and the right longitudinal beam. Lifting supports are fixedly installed at the tails of the left longitudinal beam and the right longitudinal beam. The front suspension cylinder supports, the longitudinal pull rod supports and the transverse pull rod support are fixedly installed at the front ends of the left longitudinal beam and the right longitudinal beam. A side-beam-type frame structure is formed. When the frame is matched with a hydro-pneumatic suspension in use, the frame has good adhering, buffering, shock absorbing and anti-impact performance.

Description

【Technical field】 [0001] The invention relates to the field of automobiles, in particular to a frame and a vehicle with the frame. 【Background technique】 [0002] The oil-gas suspension provides the force in two directions of tension and compression to the outside through the superposition of the comprehensive effect of internal nitrogen elasticity and hydraulic damping, and the shape displacement and velocity are variables. It has a large bearing capacity and good variable stiffness / Variable damping characteristics, so it is widely used in vehicles. [0003] At present, the 6X4 dump truck still adopts the leaf spring suspension structure. However, on the one hand, harsh roads such as mines / construction sites require a relatively large load. In order to meet the requirements of high load, 6X4 dump trucks generally increase the thickness and number of leaf springs, and the increase in the thickness and number of leaf springs reduces the suspension. The range of deformation...
