Abstract

The utility model belongs to the field of four-wheel electric vehicles, and discloses an electric four-wheel front axle which mainly comprises a front axle tube, fixed blocks, wheel hubs, arrester brakes, turning cavels and a steering arm connecting rod, wherein the turning cavels are fixedly connected with the wheel hubs; the fixed blocks are fixedly mounted at the two end parts of the front axle tube; the front axle tube is a straight tube; the axis of the front axle tube and the axis of the wheel hubs are in the same straight line; sleeve tubes at the two ends of the front axle tube are sleeved on the steering shaft of the turning cavels; the turning cavels are hinged to the front axle by utilizing a master pin; the wheel hubs are supported by the turning cavels through a pair of wheel hub bearings to realize the turning; and the arrester brakes are mounted in the wheel hubs. Through the adoption of the production, the front axle has the advantages that the turning of the left tyre and the right tyre can be enabled to be synchronous; the tyres cannot block each other; the stability is good; the transversal stability performance is enhanced; the relative jerk value of the left and the right wheel cannot be enabled to be large; the adverse effect on the vehicle body is reduced; the relative position is fixed; the front axle cannot move anywhere; the abrasion of the wheels is reduced; the service life is prolonged; the structure is simple; and the practicability is very good.

Description

A kind of electric four-wheeled propons

Technical field

The utility model belongs to the four-wheel electric motor car field, especially a kind of electric four-wheeled propons.

Background technology

Propons is meant that the vehicle front has the axletree of the function of turning to, and is the device that connects front vehicle wheel, propons mainly play engine power through the clutch transmission reduction of speed increase turn round after, be delivered to effect on the wheel by forerunner's axle assembly; Also play the effect that is used for turning to and carrying complete vehicle weight, promptly, vehicle body and front overhang are linked on the front axle assy, play the carrying effect by the leverage link.Propons mainly comprises shock-proof spring, deflector, balance shaft etc., traditional propons is that the wheel with both sides couples together with material of construction, make the wheel of the right and left produce correlation, the problem that existing propons exists is: because the wheel of the right and left can not reach synchronous working, can aggravate the wheel wearing and tearing, exist certain potential safety hazard; Lateral stability is poor, and the relative jerk value of left and right wheels is big, has increased the adverse effect to vehicle body to a certain extent.

Summary of the invention

The purpose of this utility model provides a kind of electric four-wheeled propons, to solve the asynchronous work of the right and left wheel of the prior art, can aggravate problems such as wheel wearing and tearing and lateral stability difference.

The utility model mainly comprises preceding bridge tube, fixed block, wheel hub, drg, turns to goat's horn and spindle arm connecting rod, turn to goat's horn to captive joint with wheel hub, the both ends of preceding bridge tube are installed with fixed block, solve technical scheme that its technical matters adopts and be described before bridge tube be a straight tube, the axis of preceding bridge tube and the axis in-line of wheel hub, the casing pipe sleeve at preceding bridge tube two ends is contained on the steering shaft that turns to goat's horn.

The described goat's horn that turns to utilizes stub and front axle hinged, and is supporting wheel hub through a pair of hub bearing, is used for realizing turning to.

Described drg is installed in the wheel hub.

Adopt the good effect that the utility model had to be: after adopting the utility model product, two tyre revolution are not eaten tire, good stability to synchronously about making; Strengthened the lateral stability performance, two relative jerk values of wheel are not excessive about can not making, and reduced the adverse effect to vehicle body; Relative position is fixed, and does not touch, and has alleviated the wearing and tearing of wheel, has prolonged service life; Simple in structure, and very practical.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

The specific embodiment

The utility model is further described with specific embodiment below in conjunction with accompanying drawing:

As shown in Figure 1: a kind of electric four-wheeled propons, mainly comprise preceding bridge tube 2, fixed block 3, wheel hub, drg, turn to goat's horn 1 and spindle arm connecting rod, turn to goat's horn 1 to captive joint with wheel hub, the both ends of preceding bridge tube 2 are installed with fixed block 3, above-mentioned preceding bridge tube 2 is a straight tube, for the work of two wheels about guaranteeing synchronous, the axis of bridge tube 2 and the axis in-line of wheel hub before requiring, the casing pipe sleeve at preceding bridge tube two ends is contained on the steering shaft that turns to goat's horn 1, two tires are reached turn to synchronously, do not eat tire, and good stability.

As improvement of the present utility model, the above-mentioned goat's horn 1 that turns to utilizes stub and front axle hinged, and is supporting wheel hub through a pair of hub bearing, is used for realizing the function that turns to, and further, above-mentioned drg is installed in the wheel hub, no longer protrudes the outside of wheel hub.

In conjunction with the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; in the ken that those skilled in the art possessed; can also make various conversion under the prerequisite that does not break away from the utility model aim, such conversion all drops within the protection domain of the present utility model.

Claims
