Embodiment 1

[0018] Embodiment 1: see figure 1 , figure 2 , a wire-type shift lever, comprising a vertically arranged shift lever body 1, a cable pulley 2 is arranged at the lower end of the shift lever body 1, and the edge of the pullwire pulley 2 is fixed to the shift lever body 1, And its length direction coincides with the radial direction of the cable reel 2; the structure is more reasonable, and it can better drive the cable reel 2 to rotate. The edge of the wire reel 2 is provided with a line groove 3 along the circumference of the wire reel, and the wire groove 3 covers at least the lower half of the edge of the wire reel 2; by arranging the wire groove 3, it can be ensured that the wire is always located in the wire groove 3 during the moving process, thereby ensuring Stability of wire movement. A pin shaft 4 is arranged in the wire slot 3 , the length direction of the pin shaft 4 is consistent with the width direction of the wire slot 3 , and its two ends are fixed to the two ...

Embodiment 2

[0021] Example 2, see image 3 , different from Embodiment 1, a rod 5 is arranged radially on the edge of the cable reel 2, and the angle between the rod 5 and the shift rod body 1 is less than or equal to 90°, and the rod 5 One end away from the cable reel 2 has a through groove, the center line of the through groove and the center line of the wire groove on the pull wire reel are on the same plane; the pin 4 is located between the shift lever body 1 and the support rod 5; Better tensioning of the cable and less rotation of the shifter body.

Abstract

The invention discloses a pulling wire type gear lever which comprises a gear lever body vertically arranged. A pulling wire disc is arranged at the lower end of the gear lever body. The gear lever body is fixed to the edge of the pulling wire disc and the length direction of the gear lever body coincides with the radial direction of the pulling wire disc. A wire groove is formed in the edge of the pulling wire disc in the circumferential direction of the pulling wire disc. At least the lower half edge of the pulling wire disc is covered with the wire groove. A hinge pin is arranged in the wire groove. The length direction of the hinge pin is identical to the width direction of the wire groove and the two ends of the hinge pin are fixed to the two side walls of the wire groove. The pulling wire type gear lever is simple in structure and capable of rapidly driving a shifting fork to move so that the response speed in the gear shifting process can be improved.

Description

technical field [0001] The invention relates to a vehicle gear shift mechanism, in particular to a pull-wire type gear shift lever for an electric tricycle. [0002] Background technique [0003] Known electric tricycle is to directly drive wheel to rotate by electric motor by chain and sprocket, does not have speed change device, thereby can not change speed. Therefore someone has designed the gearbox that is used for electric tricycle, and in order to make operation simple, the gear position of electric vehicle gearbox generally only has two gears, high and low, and the gear is replaced by a shift fork. The existing electric tricycle transmission gear replacement system generally consists of a shift fork shaft, a shift fork sleeved on the shift fork shaft, a return spring sleeved on the shift fork shaft and positioned between the shift fork and the box body, and The shift lever mechanism is installed on the car body through the bracket, and is connected with the shift fo...
