CN202782507U - Front axle structure of automobile - Google Patents

Abstract

The utility model discloses a front axle structure of an automobile. The front axle structure of the automobile comprises a through beam and a steering oil cylinder installation support frame is arranged in rear of the through beam. The steering oil cylinder installation support frame is additionally arranged on the through beam so that the steering oil cylinder is stably fixed on the through beam so as to improve rigidity and steering sensitivity of a steering system. The steering oil cylinder installation beam is arranged in rear of the through beam so that part of the parts of the steering system is correspondingly moved backwards by a distance and a space is not jammed in the front of a frame. Parts in the front of the frame can be favorably arranged in a reasonable mode, and wide gaps are reserved among the parts so that the requirement for precision in machining parts is lowered. The front axle structure of the automobile is simple in structure, convenient to install and provides a suitable fixation position for the steering oil cylinder and at the same time, effectively solves the problem of a narrow installation space in the front of a frame of a traditional front axle structure.

Description

A car front axle structure

technical field

The utility model relates to body parts, in particular to an automobile front axle structure.

Background technique

At present, the steering system commonly used in automobiles realizes the steering function by connecting the steering drop arm to the steering straight rod, and the steering straight rod is connected to the joint arm of the steering front axle to realize the steering function. However, this steering system has an intermediate transmission link, and the steering drop arm The processing and installation requirements of high precision, and increase the steering transmission resistance, so that the whole vehicle turns heavy when turning, and the phenomenon of poor alignment; The components are all arranged on the same side of the front of the frame, resulting in a relatively narrow space for this location, small gaps between the components, and high requirements for the machining accuracy of the components. Interference is prone to occur. Therefore, it is necessary to design a steering system that uses the steering cylinder to realize the steering function after canceling the steering pendant arm and the steering straight rod. However, different steering systems must be equipped with corresponding front axles to avoid interference between parts. Mutual interference to improve the flexibility of the steering system of the car, and finally ensure the safety of the vehicle, so designing a suitable front axle structure has become an urgent problem to be solved.

Utility model content

The purpose of the utility model is to provide a new automobile front axle structure, which facilitates the installation and fixation of the steering oil cylinder, thereby improving the sensitivity of the steering system and the rationality of its arrangement.

The solution adopted by the utility model is: a car front axle structure, which includes a through-beam, and the rear part of the through-beam is provided with a steering oil cylinder mounting bracket.

The traditional through-beam of the front axle is an ordinary I-shaped structure. When the steering system of the automobile adopts the form of the steering cylinder, the steering cylinder cannot be properly installed. On the through-beam, the stiffness and steering sensitivity of the steering system are improved; the steering cylinder mounting bracket is set at the rear of the through-beam, so that some parts of the steering system are moved back for a certain distance, so that the front of the frame does not As for being too crowded, it is conducive to the reasonable arrangement of the front parts of the frame, leaving a large gap between the parts, thereby reducing the requirements for the processing accuracy of the parts; the utility model has a simple structure and is easy to install. It not only ensures a suitable fixing position, but also effectively solves the problem of narrow installation space at the front of the frame when the traditional front axle structure is adopted.

Preferably, the steering cylinder mounting bracket is a flat support plate, the rear edge of the support plate is fixed on the rear side wall of the through beam, and a through hole is opened on the support plate. The tail of the steering oil cylinder is placed on the supporting plate, and the tail of the steering oil cylinder is connected with the supporting plate with a connecting piece at the through hole to realize fixing.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, so as to understand the utility model more clearly, but they do not limit the utility model.

As shown in Fig. 1 and Fig. 2, the utility model includes an I-shaped through-beam 1, and a steering oil cylinder mounting bracket 2 is arranged at the rear of the through-beam 1, and the steering oil cylinder mounting bracket 2 is a plane square supporting plate, which supports The rear edge of the plate is welded on the side wall at the center position of the rear part of the through-beam 1, and a circular through hole is opened on the supporting plate.

As shown in Figure 3, the working process of the present utility model is as follows: the afterbody of the steering oil cylinder 4 of the automobile steering system is installed on the steering oil cylinder mounting bracket 2 by bolts, the head of the steering oil cylinder 4 is connected with the steering knuckle arm 3, and the head of the steering oil cylinder 4 When the piston rod 5 at the top stretches, the steering knuckle arm 3 swings accordingly to drive the tire to rotate, and the utility model then plays the role of fixing the steering cylinder 4 afterbody.

Claims (2)
