Abstract
The utility model provides a vehicle axle structure which comprises an axle head and an axle body, wherein the axle head and the axle body are integrally molded, and a pair of clamping and mounting platforms is arranged in parallel at the junction of the axle body with a suspension. On the basis of the engagement of the two-square two-round structure of the vehicle axle and an axle seat which is arranged on a suspension supporting beam, the axle body and the suspension are firmly connected, and simultaneously bolts for fixing the axle body and the suspension supporting beam are not needed, so as to avoid the hidden problem that the bolts are liable to failures after long-term use, meet the highway safety requirements in United States and other countries and provide sufficient guarantee for the export of vehicle axles.
Description
Technical field
The utility model relates to automobile technical field, more particularly, relates to a kind of axle construction.
Background technology
The traveling gear of automobile comprises suspension and axletree, hangs to be installed between axletree and the vehicle frame, and its effect is flexibly to connect axletree and vehicle frame, relaxes the impulsive force that vehicle is subjected in travelling, and play the guiding role.During connection, axletree is connected with suspension, and suspension connects to ground.The leaf spring that is hung with commonly used at present hangs and Pneumatic Suspension, and Pneumatic Suspension hangs the ride comfort and the traveling comfort that more can improve running car than leaf spring, has improved the shipping goods safety, and reduces the damage to highway pavement, play the effect of maintaining public highway, thereby obtain more applications gradually.On current superimposed trailer world market, the connecting structure that hangs with axletree all is to clamp with U-bolt basically, again with welding manner with circle or square fixed axle on suspension, to reach anti-rotation and to prevent the purpose of axletree end float misalignment.Particularly on Pneumatic Suspension, with being connected of superimposed trailer axletree all is to adopt welding manner basically, the producer that has adds U-bolt both is tied on the basis of welding, this mode shortcoming be near the defective that axis body cracking occurs even lost efficacy easily the position of weld; At present, some country has put into effect regulation, uses this frame mode that axletree and suspension is linked together with bolt on the restricting vehicle.
The utility model content
The technical problems to be solved in the utility model is, pass through the existing technological deficiency of bolted connection at hanging in the prior art with circular shaft, a kind of axle construction that bolt together is hung is provided, has thoroughly stopped the present Bolt Connection traffic hidden danger of accidents happened to easily.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of axle construction, comprise spindle nose and axis body, and described spindle nose and axis body global formation, described axis body are provided with the clamping erecting stage of pair of parallel at the position that connects with suspension.
In the above-mentioned axle construction, the terminal circular arc of described parallel clamping erecting stage connects.
In the above-mentioned axle construction, described axis body is suitable at the profile and the described axle bed that connect the axle bed position.
In the above-mentioned axle construction, described axis body and axle bed are along the whole outer rim welding of axle bed.
The beneficial effects of the utility model are:
At axle construction of the present utility model, cooperate with axle bed on the suspension strut beam by the structure of axletree two sides two circle, when reaching axis body and hanging firmly connection, cancelled the bolt of rear end plate of axis body and suspension strut beam, avoided the troublesome hidden danger of bolt long-term use, reach the highway safety requirement of country such as U.S., for the outlet of axletree provides full guarantee.
Description of drawings
Fig. 1 is the utility model axle construction scheme drawing;
Fig. 2 is the lateral plan of axletree shown in Figure 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, axle construction of the present utility model is made of spindle nose 1, axis body 2, and spindle nose 1 is Integratively formed with axis body 2, and spindle nose 1 and axis body 2 process by solid drawn pipe.Suspension is made up of following major part: pendulum spring, spring cushion block, support beam, bumper, axle sleeve hole, front frame and axle bed.Its central axis seat is packed on the axis body of axletree, axletree and axle bed weld together, and the realization axletree connects with suspension.
Axletree is the root circular shaft, axis body is being provided with the zone that connects with axle bed near the place, both sides, this zone is being the quadrangle of two sides, two circles with the cross-sectional plane that hangs the position that connects, wherein parallel, the other one group of opposite side of two opposite side is a circular arc, axis body squeezes out two at the position that connects with suspension and clamps installed platform 3, two platforms are parallel, and the profile of axle bed is a circular arch door shape, and are just suitable with the cross section of two sides two circle of axis body.The cross-sectional plane of axle bed is a dome-shaped, ring is fitted with three outer walls of axis body in it, axis body and axle bed are along the whole outer rim welding of axle bed, form a circle osed top fillet weld, can prevent axletree and hang generation circumferential and axial relative displacement, and can prevent that axis body from rotating and axially scurrying the position relative to the suspension strut beam.
Claims (4)
1. an axle construction comprises spindle nose (1) and axis body (2), and described spindle nose and axis body global formation is characterized in that: described axis body is provided with the clamping erecting stage (3) of pair of parallel at the position that connects with suspension.
2. axle construction according to claim 1 is characterized in that: the terminal circular arc of described parallel clamping erecting stage (3) connects.
3. axle construction according to claim 2 is characterized in that: described axis body (2) is suitable at the profile and the described axle bed that connect the axle bed position.
