The gearshift lubrication structure comprises a gearshift shaft which is arranged inside a casing and can slide along the axial direction inside the casing. A blind hole is arranged on the inner wall surface of the casing, the gearshift shaft is glidingly supported inside the blind hole through a linear bearing, and an oil guide hole communicating the inner end surface of the linear bearing and the inner cavity of the casing is formed at the bottom part of the blind hole.
Description
Technical field
The utility model relates to a kind of speed changer lubricating structure, relates in particular to a kind of shifting of transmission lubricating structure.
Background technique
Manual transmission generally is mounted between clutch and the transmission shaft; recently change vehicle drive force and speed by changing transmission; to adapt to the driving conditions of frequent variation; need manual transmission is carried out gear-change operation for this reason; and gear-change operation accurately and smooth and easy be to improve vehicle to take advantage of the important indicator of driving travelling comfort; manual speed transmission shifting mechanism on the present car; generally be that shift shaft is directly installed in the mounting hole of housing correspondence; accurate in order to ensure gear-change operation; smooth and easy; often with mounting hole that shift shaft cooperates in inject a large amount of lubricant oil; though so can guarantee the two enough lubricating arranged; resistance when but having increased the relative mounting hole of shift shaft and endwisely slipping, thus also can't effectively guarantee gear-change operation accurately and smooth and easy.
As Chinese patent: " lubricating structure of manually shifted transmission (CN1651806A) " discloses a kind of lubricating structure of manually shifted transmission, this speed changer has a control room, this control room is positioned at case of transmission top and wherein is provided with a Control Shaft, the open part that leads to the control room is formed on case of transmission top, and at least one drain oil arranged in that open part is other, the oil that enters the control room by open part can be drained.This device is by a control room that has Control Shaft is set on case of transmission, and drain oil is set at the connection opening place of control room and case of transmission, and by the indoor lubricant oil of this drain oil emission control at any time, to guarantee the accurate and smooth and easy of gear-change operation, complex structure, the speed changer volume is increased, and increased cost of material and processing cost, be not suitable for popularization and application on various vehicles.
Summary of the invention
The utility model mainly provided a kind of simple in structure, cost is low, can guarantee that shift shaft obtains enough lubricating, and effectively guarantee gear-change operation accurately and smooth and easy, take advantage of the travelling comfort of driving thereby improved, and shifting of transmission lubricating structure that can popularization and application on various vehicles.Solve the lubricating structure complexity, the cost height that exist in the prior art, thereby be not suitable for the technical problem of popularization and application on various vehicles.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of shifting of transmission lubricating structure, comprise be located in the housing and can be in housing shift shaft in axial sliding, on the internal face of described housing, be provided with blind hole, described shift shaft is slidably supported in the blind hole by linear bearing, is provided with the oil guiding hole of conducting between linear bearing interior edge face and housing inner chamber in the bottom of described blind hole.Fix shift shaft by the blind hole that linear bearing is housed in the inwall setting of housing, simple in structure; Again by between the bottom of blind hole and housing inner chamber, oil guiding hole being set, when shift shaft endwisely slips along blind hole, can get rid of from the lubricant oil that housing inner chamber absorption lubricant oil maybe will accumulate in the blind hole at any time by oil guiding hole, when having guaranteed that shift shaft has obtained enough lubricating, balance the shift shaft resistance that endwisely slips, thereby effectively guaranteed the accurate and smooth and easy of gear-change operation, improved and taken advantage of the travelling comfort of driving, and need not increase assisting agencies such as control room, cost is low, is adapted at popularization and application on the various vehicles.
As preferably, described oil guiding hole is located on the wall of housing inner chamber, and an end links to each other with the linear bearing interior edge face in the corresponding blind hole of described oil guiding hole.By on the blind hole wall of housing inner chamber, oil guiding hole being set, easily processing, and can shorten oil guiding hole length, it is smooth and easy to guarantee that lubricant oil flows between blind hole and housing inner chamber, guarantees the accurate and smooth and easy of gear-change operation; By oil guiding hole is linked to each other with the interior edge face of linear bearing, guarantee that linear bearing passes through oil guiding hole fuel feeding and oil extraction efficiently, guarantee that lubrication effect and gear-change operation are accurately with smooth and easy.
As preferably, described oil guiding hole is the young bellmouth orifice of collar extension imperial palace.Inner small and outside big tubaeform oil guiding hole can guarantee under the lubricated situation, has both improved the mobile speed of lubricant oil, can guarantee that again the impurity of housing inner chamber can not enter blind hole by oil guiding hole, thereby influence normal gear-change operation.
As preferably, the diameter of described oil guiding hole is located between φ 2mm to the φ 6mm.Oil guiding hole is located between φ 2mm to the φ 6mm, and is lubricated and operating effect is good.
Therefore, a kind of shifting of transmission lubricating structure of the present utility model has following advantage: by between the location of linear bearing blind hole and housing inner chamber oil guiding hole being set, when making shift shaft obtain enough lubricating, balance the slip resistance of shift shaft, thereby effectively guaranteed the accurate and smooth and easy of gear-change operation, improved and taken advantage of the travelling comfort of driving, cost is low, is adapted at popularization and application on the various vehicles; By the oil guiding hole that links to each other with the interior edge face of linear bearing in setting on the blind hole wall of housing inner chamber, easy processing, and can shorten oil guiding hole length, thus reduce fuel feeding and oil extraction time, guarantee the accurate and smooth and easy of gear-change operation; Inner small and outside big tubaeform oil guiding hole had both improved the mobile speed of lubricant oil, can guarantee that again the impurity of housing inner chamber can not enter blind hole by oil guiding hole, guaranteed the normal running of gear-change operation.
