Abstract

The invention relates to a flexible axle assembly, which comprises an axle housing (9), an axle head (3), a hub (1) and a braking device (2), and is characterized in that positioning blocks (10) are symmetrically arranged on two inner sides of the axle housing (9) respectively, each positioning block (10) is fixedly connected with one end of a torsion spring (11), the other end of the torsion spring (11) extends out of the axle housing (9) and is fixedly connected with second positioning blocks (5), a guide sleeve (8) is fixedly sleeved on the second positioning blocks (5), one portion of the guide sleeve (8) extends into the axle housing (9), a supporting sleeve (7) is arranged between the guide sleeve (8) and the axle housing (9), and a swing arm (4) is fixedly sleeved on the other portion of the guide sleeve (8) and fixedly connected with the axle head (3). The flexible axle assembly has the advantages that a suspension system between an axle and a frame is omitted, bearing height and gravity center height of a vehicle are effectively reduced, and damping performance when the vehicle runs on or passes through uneven road surfaces can be effectively enhanced, so that stability of the vehicle during running is improved.

Description

A kind of flexible axle unit

Technical field

The present invention relates to a kind of device that is applied to small-sized towed vehicle vehicle, especially a kind of flexible axle unit.

Background technology

Common axle unit is made up of other parts such as axletree, brake system, wheel hub, and its axletree is the rigidity integrative-structure, and promptly the spindle nose of axletree and axis body are through being welded; Axletree connects with vehicle frame through suspension system, and vibration-damping function mainly leans on suspension system to realize that this structure vehicle goods platform carrying surface is high, and vehicle's center of gravity is also high, and riding stability is poor.

Summary of the invention

The object of the invention is exactly to connect with vehicle frame through suspension system in order to overcome existing axletree, the defective that vibration-damping function mainly leans on suspension system to realize, and a kind of flexible axle unit is provided.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of flexible axle unit; Comprise axle housing, spindle nose, wheel hub, brake equipment; It is characterized in that: bilateral symmetry is respectively equipped with fixing locating piece in the axle housing, and every side locating piece is captiveed joint with an end of torque spring, and the other end of torque spring stretches out the axle housing outside captives joint with locating piece two; Fixing guide pipe of suit on the locating piece two; The part of guide pipe stretches in the axle housing and between guide pipe and axle housing and is provided with supporting sleeve, fixing sheathed swing arm on another part of orienting sleeve, and described swing arm is captiveed joint with spindle nose.

On the basis of above-mentioned main technical schemes, can increase following further perfect technical scheme:

Described torque spring, locating piece two, guide pipe, swing arm are through a locking bolt captive joint.

Described supporting sleeve is provided with oilhole, increases the lubricated of guide pipe.

The invention has the beneficial effects as follows the suspension system of removing between axletree and the vehicle frame, effectively reduce vehicle and carry height and height of gravitational center that the cushioning performance in the time of solving vehicle ' simultaneously again well or pass through uneven road surface further improves the stationarity of vehicle operating.

Below in conjunction with accompanying drawing and embodiment the present invention is further specified.

Description of drawings:

Fig. 1 is a front view of the present invention;

Fig. 2 is a lateral plan of the present invention.

The specific embodiment

As depicted in figs. 1 and 2, a kind of flexible axle unit of the present invention, wheel hub 1 is identical with common axle unit with brake equipment 2, is the basic components of walking of this device and braking; Spindle nose 3 is fixedly connected with swing arm 4, and guide pipe 8 is fixedly connected spindle nose 3, swing arm 4, locating piece 25 and guide pipe 8 composition left and right sides bent axle parts with locating piece 25 and swing arm 4; Wherein locating piece 25 has interior square hole; Supporting sleeve 7 is fixedly connected with locating piece 10 and axle housing 9, and connection seat 12 is fixedly connected with axle housing 9, and supporting sleeve 7, axle housing 9, locating piece 10 are formed axis body; Wherein locating piece 10 has interior square hole, and axis body is the foundation support parts of the flexible axletree of this machine; Torque spring 11 is packed in the square hole of locating piece 25 of locating piece 10 and bent axle of axis body, and torque spring 11 is captiveed joint with locating piece 10, and relative positioning piece 25 and locating piece 10 are motionless; Left and right sides bent axle is packed in the supporting sleeve 7 of axis body, and connects with torque spring 11, and contacts with the end face of axis body, and is fixing together bent axle and torque spring 11 through locking bolt 6, and bent axle relative axis body in the left and right sides must not be moved axially; Left and right sides bent axle, axis body and torque spring are formed flexible axletree, and locating piece 10 two ends in the middle of the torque spring 11 relative axis bodies produce rotational deformation, and bent axle relative axis body in the left and right sides is rotatable; And supporting sleeve 7 is provided with oilhole, increases the lubricated of guide pipe 8, and the connection seat 12 and the carriage frame of axis body are connected and fixed; This machine and vehicle frame be linked together, effectively reduce vehicle goods platform carrying surface height, reduce the vehicle's center of gravity height; Improve vehicle run stability, vehicle carries or during through uneven road surface, torque spring 11 relative positioning pieces 10 produce rotational deformations; Drive left and right sides crankshaft revolution swing, realize the Vehicle damper function, reach the stationarity of vehicle '.
