Problems solved by technology

However, the AGV car also has the following disadvantages: 1. The steering mechanism of the AGV car is directly driven by the motor to steer the hub, so the steering torque is large, the response speed is slow, and it is difficult to accurately control
2. AGV cars generally use track navigation or laser navigation, and operate at low speeds, with low accuracy
[0004] Therefore, it is difficult for the AGV trolley to serve as the target vehicle carrying platform

Embodiment 1

[0041] A chassis trolley of a carrying vehicle comprises a chassis, a driving mechanism, a steering mechanism, a left steering wheel set, a right steering wheel set and a driving wheel set. In this embodiment, the steering mechanism, the left steering wheel set and the right steering wheel set are arranged at the front of the chassis, and the driving mechanism and the driving wheel set are arranged at the rear of the chassis.

[0042] Such as figure 1 and figure 2 As shown, the left steering wheel set includes the left steering wheel 9, the left turning lever 1 and the left fixed piece 7; the right steering wheel set includes the right steering wheel, the right turning lever and the right fixing piece; the left steering wheel 9 and the right steering wheel They are respectively arranged on the left and right sides of the front part of the chassis.

[0043] Specifically, take the left steering wheel 9 as an example, the left fixed piece 7 is a triangle, the left turning rod ...

Embodiment 2

[0057] A trolley with a chassis of a carrying vehicle is different from Embodiment 1 in that it further includes two brake mechanisms. Both the left steering wheel set and the right steering wheel set correspond to a braking mechanism. The left turning rod 1 rear end is provided with a rotating shaft hole along the axis of the left steering wheel 9.

[0058] Such as Figure 5 As shown, taking the brake mechanism corresponding to the left steering wheel set as an example, the brake mechanism includes a hydraulic caliper 14, a brake pad 15, a brake shaft 16, a telescopic rod 17, two universal joints and a front shaft 18. Front rotating shaft 18 passes through the rotating shaft hole, and one end of front rotating shaft 18 is welded with left steering wheel 9, and the other end of front rotating shaft 18 is connected with an end of telescopic rod 17 by a universal joint, and the other end of telescopic rod 17 passes through another universal joint. Joint is connected with one e...

Embodiment 3

[0062] A chassis trolley of a carrier vehicle, the difference from Embodiment 1 is that the push rod adopts a hydraulic push rod.

[0063] It also includes a detection mechanism, which includes a temperature sensor, a hydraulic sensor, a processing unit and an alarm unit; the temperature sensor is bonded to the casing of the hydraulic push rod to detect the temperature at the shell of the shock absorber; the hydraulic sensor is bonded to the hydraulic push rod The inside of the rod, used to detect the hydraulic pressure inside.

[0064] The processing unit is signal-connected with the temperature sensor and the hydraulic pressure sensor, and the processing unit is used for receiving the temperature signal of the temperature sensor and the hydraulic pressure signal of the hydraulic pressure sensor. The temperature threshold and the hydraulic threshold are pre-stored in the processing unit; the processing unit is used to compare the temperature signal with the temperature thresh...

Abstract

The invention relates to the technical field of bearing vehicles, specifically to a bearing vehicle chassis trolley. The bearing vehicle chassis trolley comprises a chassis, a steering mechanism, a left steering wheel set and a right steering wheel set; the steering mechanism, comprises a left connecting rod, a first middle connecting rod, a shifting fork, a push rod, a second middle connecting rod and a right connecting rod; the left steering wheel set is rotationally connected with the left end of the left connecting rod; the right end of the left connecting rod is rotationally connected with the left end of the first middle connecting rod; the right steering wheel set is rotationally connected with the right end of the right connecting rod; the left end of the right connecting rod is rotationally connected with the right end of the second middle connecting rod; the shifting fork comprises a left end, a right end and a raised end which are integrally molded; the left end and the right end of the shifting fork are correspondingly and fixedly connected to the right end of the first middle connecting rod and the left end of the second middle connecting rod; the push rod is arrangedparallel to the first middle connecting rod and the second middle connecting rod; the push rod comprises a tail end and a movable end; the tail end is fixedly connected to a chassis; and the movable end is rotationally connected to the raised end of the shifting fork. The technical scheme of the bearing vehicle chassis trolley has the advantages that the structure is compact, the steering is flexible and the bearing vehicle chassis trolley can be accurately controlled.

Description

technical field [0001] The invention relates to the field of carrier vehicle technology, in particular to a carrier vehicle chassis trolley. Background technique [0002] At present, in the test of the Advanced Driver Assistant System (ADAS, Advanced Driver Assistant System) of the car, including the test of the Automatic Emergency Braking System (AEB, Autonomous Emergency Braking System) and the test of the Adaptive Cruise Control System (Adaptive Cruise Control System, referred to as ACC) , Lane Departure Warning System (LDW) test and forward collision warning system (ForwardCollision Warning, FCW) test and other sub-tests, these sub-tests need to simulate the motion state of pedestrians and vehicles, for which a set of dedicated As the platform for the target vehicle, the target-carrying robot needs to have the characteristics of stable high-speed movement, precise path control, good acceleration and deceleration performance, and long cruising range. [0003] The overall...
