Problems solved by technology

Most of these mechanisms have the problem of being unable to engage gears when they are parked, turned off, or at high speeds. Pneumatic and hydraulic mechanisms are highly dependent on pressure sources, require high installation, and have a risk of leakage.

Embodiment Construction

[0025] This embodiment is a vehicle with a differential lock operating device. The differential lock operating device is used to engage and separate the sliding engagement sleeve 5 from the fixed engagement sleeve 6, wherein the sliding engagement sleeve 5 is splined to the half shaft 8 and can be Move axially along the half shaft 8; the fixed engagement sleeve 6 is connected to the differential case 7 through a spline, and the fixed engagement sleeve 6 is axially fixed and rotates together with the differential case 7 (see figure 1 ).

[0026] Such as figure 2 , image 3 As shown, the differential lock operating device in this example has an operating mechanism, a buffer accumulator 2 and a transmission mechanism. The energy device 2 and the transmission mechanism drive the sliding engagement sleeve 5 to move axially along the half shaft 8 to realize the engagement and separation of the sliding engagement sleeve 5 and the fixed engagement sleeve 6 .

Abstract

The invention relates to a differential lock control device and a vehicle and aims at providing the differential lock control device which is simple in structure, safe, reliable and convenient to install and the vehicle. Through the differential lock control device, locking and separation of a differential mechanism can be achieved in various states, and torque distribution between wheels can be effectively achieved, so that the vehicle adapts to various bad road conditions. According to the technical scheme, the differential lock control device is used for enabling a sliding engagement sleeveand a fixed engagement sleeve to be engaged or disengaged, wherein the sliding engagement sleeve is used for being connected with a half axle through a spline and can move in the axial direction of the half axle; the fixed engagement sleeve is used for being connected with a differential mechanism shell. The differential lock control device is provided with an action mechanism, a buffer energy accumulator and a transmission mechanism; the action end of the action mechanism is connected with the sliding engagement sleeve through the buffer energy accumulator and the transmission mechanism in sequence; the action mechanism drives the sliding engagement sleeve to move in the axial direction of the half axle through the buffer energy accumulator and the transmission mechanism to achieve engagement and disengagement of the sliding engagement sleeve and the fixed engagement sleeve. The differential lock control device is applicable to the field of differential locks.

Description

technical field [0001] The invention relates to a differential lock operating device and a vehicle. Suitable for differential lock field. Background technique [0002] At present, the differentials used on forklifts generally have the characteristic of "differential speed without torque", which has an adverse effect on the driving of the vehicle. For example, when one wheel is stuck in mud, it will slip due to insufficient adhesion. , At this time, the driving force of the other wheel will not increase, but will decrease, resulting in a significant reduction in the traction force of the vehicle. [0003] In order to improve the passability of the vehicle and meet the needs of four-wheel drive off-road forklifts, a differential lock is installed on the bridge, which can effectively solve the problem of "differential speed does not cause torque". Considering the heavy and low speed characteristics of forklifts, manual mechanical differential locks (jaw type) are often used. ...
