Description
Technical field
The utility model relates to gear box hydraulic control technique field, particularly a kind of static state make the return trip empty gear process reduce impact structure.
Background technique
Static shift shock refers to that car load is in startup, during stationary vehicle, when manual rod is linked into P/N gear by D/R gear, and the impact of generation.
At present, the shift process of R/D to N, R to P in static shift process, corresponding clutch internal drainage process controls draining speed by automatical control system.
But electric control system controls requires that the electronic component control accuracies such as solenoid valve are higher, and cost is higher, and automatically controlled control stability is poor, easily breaks down simultaneously.
Model utility content
In view of this, the utility model provide a kind of static state make the return trip empty gear process reduce impact structure, to improve the stability in shift process.
For achieving the above object, the utility model provides following technological scheme:
A kind of static state gear process of making the return trip empty reduces impact structure, comprises gearshift solenoid valve, shift valve, clutch, manually operated valve and corresponding oil circuit, is provided with accumulator in the draining oil circuit between described clutch and described manually operated valve.
Preferably, also comprise the one-way valve be arranged between described clutch and described manually operated valve in draining oil circuit, and described one-way valve is to described manually operated valve one-way conduction by described clutch.
Preferably, the cavity volume size of described accumulator is adjustable.
Preferably, the spring force value size of described accumulator is adjustable.
As can be seen from above-mentioned technological scheme, the static state that the utility model provides gear process of making the return trip empty reduces impact structure, by increasing accumulator on clutch oil circuit, can effectively slow fluid draining speed, from having cushioned static shift shock; Compared with automatical control system of the prior art, the mechanical structure that this programme adopts has higher stability, and cost is not high, is easy to realize and safeguard.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 reduces the schematic diagram of impact structure for static state that the utility model embodiment provides gear process of making the return trip empty.
Wherein, 1 is gearshift solenoid valve; 2 is shift valve; 3 is clutch; 4 is one-way valve; 5 is manually operated valve; 6 is accumulator; 7 is oil sump; 8 is the first oil circuit; 9 is the second oil circuit; 10 is the 3rd oil circuit.
Embodiment
The utility model discloses a kind of static state make the return trip empty gear process reduce impact structure, to improve the stability in shift process.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, Fig. 1 reduces the schematic diagram of impact structure for static state that the utility model embodiment provides gear process of making the return trip empty.
The kind static state that the utility model embodiment provides make the return trip empty gear process reduce impact structure, comprise gearshift solenoid valve 1, shift valve 2, clutch 3, manually operated valve 5 and corresponding oil circuit, in this programme, corresponding oil circuit comprises the first oil circuit 8 be connected between clutch 3 and shift valve 2, be connected to the second oil circuit 9 between the first oil circuit 8 and manually operated valve 5, be connected to the 3rd oil circuit 10 between manually operated valve 5 and oil sump 7;
Its core improvement is, is provided with accumulator 6 in the draining oil circuit between clutch 3 and manually operated valve 5.
During static gearshift, electric control system controls gearshift solenoid valve 1, gearshift electromagnetic valve shift valve 2 pairs of clutch 3 fluid control, fluid in clutch 3 oil circuit is released, as shown in Figure 1, clutch inner fluid is by the first oil circuit 8---accumulator 6---the second oil circuit 9---manually operated valve 5---second oil circuit 10---oil sump 7
As can be seen from above-mentioned technological scheme, the static state that the utility model embodiment provides gear process of making the return trip empty reduces impact structure, by increasing accumulator 6 on the oil circuit of clutch 3, can effectively slow fluid draining speed, from having cushioned static shift shock; Compared with automatical control system of the prior art, the mechanical structure that this programme adopts has higher stability, and cost is not high, is easy to realize and safeguard, is applicable to a grade process of making the return trip empty of R/D to N, R to P in static shift process.
Further, the static state that the utility model embodiment provides make the return trip empty gear process reduce impact structure, also comprise the one-way valve 4 be arranged between clutch 3 and manually operated valve 5 in draining oil circuit, and this one-way valve 4 is by clutch 3 to manually operated valve 5 one-way conduction, to optimize the flow direction of oil circuit.
In the specific embodiment that this programme provides, the cavity volume size of accumulator 6 is adjustable.Similar, the spring force value size of accumulator is adjustable.By regulating accumulator cavity volume and accumulator spring force value size, effectively can slow down fluid draining speed, thus alleviating static shift shock.
In sum, the static state that the utility model embodiment provides make the return trip empty gear process reduce impact structure, R/D to N in static shift process, a grade process of making the return trip empty of R to P, emptying process in corresponding clutch, for avoiding oil pressure change in emptying process too fast, reduces the impact to gearbox, clutch oil circuit increases accumulator structure, improves stability in shift process; Compared with automatical control system of the prior art, the mechanical structure that this programme adopts has higher stability, and cost is not high, is easy to realize and safeguard.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
