Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, working principle of the present utility model is:
The utility model has been realized the gearshift location, the functions such as neutral location, block selecting return, block selecting sense power, generation block selecting power and generation gear shifting force (the enhancing gearshift sucks and feels).Shifting sense power piece 2 is fixed together by resilient key 3 and shifting shaft 4, shifting sense power piece 2 is along with the movement of shifting shaft 4 or rotation and accordingly mobile or rotate, block selecting positioning seat 1 and gearshift positioning seat 5 are fixed together by being pressed into (interference fit) or screw thread and case of transmission, block selecting positioning seat 1 and gearshift positioning seat 5 structures are same or similar, can be different with performance according to mounting type and its profile of elastic force, its internal structure mainly is comprised of several parts such as shell, spring and steel balls.Both sides are arranged respectively on the shifting sense power piece 2 one be provided with the transmission gear bits number be complementary trough " wave " shape curved surface 2-2 and be provided with " bat wing " shape curved surface 2-1 of three place's grooves.Block selecting positioning seat steel ball 1-3 rolls at " wave " shape curved surface 2-2 of shifting sense power piece 2, and along with the fluctuating of the arc surface of " wave " shape curved surface 2-2 and compress block selecting positioning seat spring 1-2, the gearshift positioning seat steel ball 5-3 of gearshift positioning seat 5 rolls at " bat wing " shape curved surface 2-1 of shifting sense power piece 2, compresses equally gearshift positioning seat spring 5-2 along with the fluctuating of " bat wing " shape curved surface 2-1.
The trough place, middle part of " wave " shape curved surface 2-2 on shifting sense power piece 2, block selecting positioning seat steel ball 1-3 is simultaneously tangent with two arc-shaped surfaces, it is the meta of speed changer block selecting herein, it is neutral gear position, during the neutral position, gearshift positioning seat steel ball 5-3 also just in time is in the medial recess place of " bat wing " shape curved surface 2-1, also simultaneously tangent with two curved surfaces, can a cancel out each other part or offset reach state of equilibrium fully of shifting shaft 4 radial force balances, the spring force that acts on the block selecting positioning seat 1 that is arranged symmetrically with on the shifting sense power piece 2 and gearshift positioning seat 5.
When the driver carries out gear shift operation, shifting shaft 4 drives shifting sense power piece 2 and rotates around the shifting shaft axis, block selecting positioning seat steel ball 1-3 is at the upper straight-line rolling of " wave " shape curved surface 2-2 of shifting sense power piece 2, " wave " shape curved surface 2-2 place does not produce axial force, Compress Spring not, " bat wing " shape curved surface 2-1 gives power along point of contact and steel ball center line connecting direction of gearshift positioning seat steel ball 5-3, this power is decomposed into along the power of shifting shaft power radially and compression gearshift positioning seat contained spring, is the gear shifting force Phd that the driver experiences along the reaction force of shifting shaft power radially.Fig. 5 represents to shift gears positioning seat steel ball 5-3 when " bat wing " shape curved surface 2-1 is in the neutral position and the state during a certain gear of gearshift.Gearshift positioning seat steel ball 5-3 slips over the peak gearshift finish after, gearshift positioning seat steel ball 5-3 arrives in the groove of " bat wing " shape curved surface 2-1, gearshift positioning seat steel ball 5-3 and two inclined-planes are tangent, the radial force that place, two point of contacts produces is protected counteracting mutually, steel ball plays positioning action, make shifting sense power piece 2 no longer stressed along bevel direction, guarantee that shifting sense power piece 2 location are more accurate, can guarantee stationarity and the inner compact sense of gearshift of shift process.
Shifting shaft 4 drive shifting sense power pieces 2 move axially when the driver carries out the block selecting operation, and block selecting positioning seat steel ball 1-3 rolls in the cambered surface of " wave " shape curved surface 2-2.Fig. 6 represents block selecting positioning seat steel ball 1-3 when " wave " shape curved surface 2-2 is in the neutral position and the state of choosing when a certain gear, for the driver, after block selecting puts in place, be that block selecting positioning seat steel ball 1-3 enters " wave " shape curved surface 2-2 trough, the pressure that " wave " shape curved surface 2-2 is subject to is block selecting power Pxd, because the effect of block selecting power Pxd has obvious step sense, make the driver feel that block selecting puts in place, at this moment shift gears, travelling comfort improves greatly, the fatigue when having reduced simultaneously driver's shift hunting.
The utility model is by the structural design of shifting sense power piece 2, utilize block selecting positioning seat 1 and gearshift positioning seat 5 to realize gearshift location, block selecting sense power location, the functions such as neutral location, block selecting return, the block selecting position that has remedied prior art is inaccurate, part is many, the defective that assembling is inconvenient.
