The purpose of this utility model is the problem at above-mentioned existence, provide on a kind of structure tube more single, the better anti-lock that also more natural being used on function, the profile is arranged on the axletree position of prizing and stealing can be arranged.

The said lock that is arranged at the axletree position of the utility model comprises the two-part structure that is arranged at the axletree position and can maintains normal-running fit each other.Wherein be positioned at axletree one end and with the relatively-stationary axis blocking body of its maintenance on be provided with one at least and can under driving, make the pintle hook lock of fore and aft motion in the surface of axis blocking body with its overhanging end by key-operated lock.Said this pintle hook lock can be bolt, the pin type structure that drives sagittal plane, lower edge or axial direction moving linearly at lock, also can be the trip type structure that is driven the form that rotates by lock, or the structure of other appropriate form.Be provided with the latch-up structure that can cooperate as block card with the overhanging end of pintle hook lock in said this axis blocking body connecting with wheel and do the suitable position place of axle bowl in relative rotation with this axis blocking body.This latch-up structure can for can with this pintle hook lock overhanging end structure, the structure of fluted body of the male type of block card mutually, or can do that block card cooperates and the structure of other appropriate form that the axle bowl is locked.

On the basis of said structure, said this axis blocking body can also adopt the version of being made up of the end-blocking body of axle bumper and its outer end, and is formed with enclosed cavity betwixt.Said lock can be arranged on this end-blocking body, can drive the pintle hook lock that rotates by lock and then can be arranged in this enclosed cavity.On axis blocking body, then should be provided with the respective openings that the overhanging end that can make this pintle hook lock is made fore and aft motion.Said this opening can be opened in the appropriate position of a certain sagittal plane direction of axis blocking body, or is opened in a certain appropriate position on its axial direction.Because axle bumper and axle bowl are the stressed friction positions in travelling, also be parts normal fragile and that change.Adopt the advantage of this kind form structure just to be, be arranged on because of lock body on the end-blocking body of axis blocking body, when changing axle bumper, only need axle bumper is separated with the end-blocking body, after only separately changing axle bumper, itself and former end-blocking body weight are newly assembled recovery get final product, thereby needn't change together with lock.The size of the volume of said this enclosed cavity in the axis blocking body can be decided according to the quantity of wherein set rotatable pintle hook lock.When the rotatable pintle hook lock in this cavity is set to two or more, and when the simple synchronization structure of lever, gear or other common type is driven synchronously by same lock, then should be respectively arranged with the opening that the overhanging end that can make each pintle hook lock is made fore and aft motion with the corresponding axis blocking body of each pintle hook lock position.Though the structure of the more single pintle hook lock of this structure is slightly complicated, helps to improve the reliable and stable degree of locking.

Can only be provided with one can be with latch-up structure that pintle hook lock overhanging end in the said axle bumper cooperates as block card the time with wheel and with axle bowl position that this axis blocking body maintains normal-running fit when above-mentioned, though under any position, all can lock to wheel, and the normal continuous rotation of wheel are restricted, but quantity according to pintle hook lock set in the axis blocking body, wheel under the lock-out state still can be in certain amplitude, even can make the gyroscopic pendulum that comes toward renaturation in the amplitude range of an about circumference.If with said this latch-up structure the matching part of axle bowl and axis blocking body along the circumferential direction be arranged to a plurality of the time, then not only still can under any position, all can realize wheel is locked, and the amplitude that can make permission wheel under the lock-out state can make to change pendular motion reduces, even can be improved the steadiness of locking greatly by locking with being completely fixed.

A because common ground on the above-mentioned existing all kinds of axletree lock constructions, be exactly all will be with the axletree enlarged diameter, therefore and cause wanting related other associated components of car body that have influence on also will corresponding thereupon change, cause the considerable influence of existing production technology and the increase that produces cost.And be not difficult to find out that by said structure the above-mentioned axletree of the utility model is locked in this another distinguishing feature on the one hand, and the structure of axletree itself can be do not influenced exactly substantially, thereby this rough sledding can be avoided, help applying.
