Abstract
The utility model relates to a motor-driven gear shifting device, comprising a gear shifting shell, a gear shifting shaft, a gear shifting finger, a motor and a shifting fork; the key points are that a torsion spring, a driving arm and a nut are arranged on the gear shifting shaft; the driving arm and the nut are connected by a pin shaft; the output shaft of the motor is connected with a screw rod driving shaft and is meshed with the nut on the gear shifting shaft; limiting bosses are arranged on the gear shafting shaft and the driving arm; the gear shifting finger is fixed on the gear shifting shaft by an elastic pin. The motor-driven gear shifting device is simple in structure and easy to manufacture; clamping stagnation is avoided due to the adoption of the torsion spring structure, the gear shifting is good in continuity and small in impaction, the service life is long, the reliability and universality are good, the motor-driven gear shifting device is used for a mechanical transmission box, and the service life of the transmission box is prolonged, the maintenance cost is reduced and the economy is good.
Description
Technical field
The utility model relates to a kind of automotive transmission, specifically establishes a kind of motor-driven gearshift.
Background technique
Conventional electric gearshift, has gear & rack structure, also has the simple motorized of manual shift structure, no matter adopts which kind of form, is all rigidly connected, and does not have flexibility excessively, causing gearshift to impact obviously, discontinuous, poor practicability.
Summary of the invention
The purpose of this utility model is the shortcoming that will overcome upper technology, provide a kind of simple in structure, continuity good, little motor-driven gearshift is impacted in gearshift.
Motor-driven gearshift of the present utility model, comprise that gearshift housing, shifting shaft, gearshift refer to, motor and shift fork, it is characterized in that: on described shifting shaft, be provided with successively torsion spring, driving arm and gearshift and refer to, gearshift refers to be fixed on shifting shaft by resilient key, torsion spring and driving arm successively empty set on shifting shaft, shifting shaft and driving arm are provided with positive stop lug boss, positive stop lug boss is spacing by two arms of torsion spring, during Rotation With Changing gear shaft, positioning block on shifting shaft is passed to torsion spring power, and torsion spring drives driving arm to rotate by the positioning block on driving arm again; Described nut is located on screw type live axle, and it is connected by bearing pin with driving arm, and the other end of driving arm is located on shifting shaft; On the output shaft of described motor, be connected with screw type live axle.
In order better to realize above-mentioned purpose:
Described gearshift refers to be fixed on shifting shaft by resilient key.
The utility model is simple in structure, easy to manufacture; Adopt torsion spring structure, there will not be clamping stagnation during gearshift, gearshift continuity is good, it is little to impact, long service life, reliability and versatility are good, for mechanical gearbox, improved gearbox long service life, reduced that maintenance cost is low, good economy performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
In figure: 1, shifting shaft, 2, declutch shift shaft.3, torsion spring, 4, gearshift housing, 5, driving arm, 6, gearshift refers to, 7, resilient key, 8, synchronizer, 9, shift fork, 10, motor, 11, screw type live axle, 12, nut, 13, tooth cover, 14, bearing pin, 15, positive stop lug boss.
Embodiment
