Invention content
First purpose of the present invention easily sets the lorry of cat ladder when being intended to provide a kind of wagon box up and down, solve existing
Lorry up and down wagon box when it is inconvenient the problem of.
Second object of the present invention is further intended to provide the torque generated during a kind of braking the big lorry for setting cat ladder,
Solve the problems, such as that the torque generated during existing freight car braking is small.
More than technical problem solves by the following technical programs：A kind of lorry for setting cat ladder, including vehicle body and support
The wheel of vehicle body, the vehicle body are equipped with driver's cabin, the wagon box and wheel shaft that load cargo, and the wheel includes tire, wheel rim and spoke
Plate, the wheel are mounted on the wheel shaft, and the wagon box includes bottom plate and lower end with the hinged side plate of bottom plate, special
Sign is that the side of the wagon box is equipped with cat ladder, and the lower end of the cat ladder is located at the top of the wheel shaft.By in wagon box
Side sets cat ladder, is readily able to climb on wagon box by cat ladder, so as to improve convenience during upper wagon box.The lower end of cat ladder
Positioned at the top of column so that the setting of cat ladder does not interfere with ability of the vehicle by road surface.
Preferably, the cat ladder band epimere and hypomere, the epimere are fixed together with the side plate, the epimere
Lower end be higher than the lower end of the side plate, the hypomere is fixed on the bottom plate, and the upper end of the epimere is less than the bottom plate
Upper end.The setting of cat ladder will not cause side plate inconvenient when turning down.
Wheel of the present invention further includes brake actuator, and the brake actuator on drag ring, end face including setting friction
The brake hoop in face and drag ring driving mechanism, drag ring driving mechanism for drive drag ring along brake hoop move axially and against
It is braked on to the rubbing surface and is detached with rubbing surface and stop braking, the brake hoop is connected to the inner circumferential of the wheel rim
It is on face and coaxial with wheel rim, the annular cooling water chamber circumferentially extended along brake hoop is equipped in the brake hoop, on the rubbing surface
Apopores equipped with several perforations annular cooling water chambers, be equipped with plug in the apopore and driving plug moves outwardly and
The closed pore spring in the apopore is blocked, plug blocks the plug during apopore and protrudes the rubbing surface.It uses
When, driving mechanism with car body is linked together, cooling water is packed into cooling water ring.It needs to drive by drag ring during brake
The rubbing surface that mechanism driving drag ring abuts to brake hoop realizes friction catch, will be stifled when drag ring abuts together with braking surface
Head driving inwardly so that apopore is opened, the outflow of the water of annular cooling water intracavitary and braking position is cooled down, to prevent from making
