Embodiment Construction

[0031] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0032] This embodiment provides a self-propelled wheel set, such as figure 1 As shown, it includes a support frame 1, a retractable oil cylinder 2, a steering mechanism, a column 4, a manual latch 5 and a walking wheel set. A semi-trailer with self-propelled function is to install the self-propelled wheel set on the semi-trailer frame.

[0033] The support frame 1 is the main structure connecting the semi-trailer frame and the walking wheel group. The top of the support frame 1 is hinged with the frame mounting seat, and the support frame 1 is pushed around its hinge point with the frame mounting seat by retracting and releasing the oil cylinder 2. Rotate to realize the lowering and retracting of the walking wheel set; the bottom end of the support frame 1 is fixedly connected with the column 4 through the rotary reducer 3; the support frame 1 is provided...

Abstract

The invention discloses a semi-trailer with a self-running function and a self-running wheel set. The self-running wheel set comprises a supporting frame, an extending and retracting oil cylinder, a steering mechanism, an upright, a bolt and a running wheel set; the supporting frame is used for connecting an external frame with the running wheel set; the top end of the supporting frame is hinged to the external frame; the bottom end of the supporting frame is fixedly connected to the upright through the steering mechanism; the running wheel set is mounted at the lower end of the upright; through extending and retracting of the extending and retracting oil cylinder, the supporting frame is driven to rotate around a hinging point of the supporting frame and the external frame so as to realize the extending and retracting of the running wheel set; two locking mechanisms are arranged on the supporting frame and correspondingly used for locking the supporting frame after the supporting frame extends and retracts in place; after the supporting frame extends in place, the running wheel set is in contact with the ground and runs under the driving of a power mechanism of the running wheel set; and when the running wheel set needs to steer, the steering mechanism is driven to rotate to drive the upright to rotate around the axis of the upright so as to realize the steering of the runningwheel set. The self-running wheel set can drive the semi-trailer to self-run and self-steer after the semi-trailer is separated from a tractor.

Description

technical field [0001] The invention relates to the technical field of road transportation, in particular to a semi-trailer with a self-propelling function and a self-propelling wheel set. Background technique [0002] The semi-trailer is used for road transportation of products, and can carry out lifting and related special operations on products without any other auxiliary lifting equipment. [0003] The existing product transport vehicle can only transport products by road, does not have the self-propelled function, and needs a tractor to pull the semi-trailer to walk. After the semi-trailer arrives at the work site, if it is towed by a tractor, the turning radius is relatively large, the passability is poor, and some narrow work areas cannot complete the scheduled transportation and transfer tasks; if it is driven manually, it is time-consuming and laborious, and it is not easy to control the driving direction. The self-propelled wheel set is required to drive the semi...
