Abstract
The utility model discloses a speed sensor subassembly of engine, include: support, support include connecting portion and installation department that the horizontal direction set up, and connecting portion are fixed on the gear chamber cap of engine, and the preceding bumper shock absorber that connecting portion are located the engine is directly over, the top dead center of preceding bumper shock absorber rather than the line at center with vertical between have a first contained angle, the installation department is equipped with speed sensor installation face, is equipped with the mounting hole on the speed sensor installation face, and the axis of mounting hole is perpendicular with speed sensor installation face, the axis of mounting hole and have the second contained angle between vertical, and first contained angle equals the second contained angle, speed sensor, speed sensor installs in the mounting hole, and speed sensor's probe is just to the top dead center of preceding bumper shock absorber. Speed sensor is located between the belt pulley of preceding bumper shock absorber and harvester, makes speed sensor's mounted position avoid the contact surface of belt with preceding bumper shock absorber, can avoid the interference of support and sensor and belt.
Description
Technical field
The utility model relates to engine art, particularly a kind of speed probe assembly of engine.
Background technology
Engine assembly is on harvester time, need to adopt belt by engine front damper and harvesterBelt pulley couples together, the line of centres of the belt pulley of front damper and harvester and the angle of horizontal directionBe 40 °-50 °, and the top dead centre of front damper (i.e. 0 direction) directly over it. The gear of engineSpeed probe support is installed on chamber cap, and speed probe support is provided with the installed surface of level, installsFace is provided with vertical installing hole, and speed probe is arranged in installing hole, and establish the lower end of speed probeHave probe, the just top dead centre to front damper of probe, makes speed probe identify the tach signal of engine.But such structure makes belt and speed probe support have interference problem.
The information that is disclosed in this background technology part is only intended to increase to general background of the present utility modelUnderstand, and should not be regarded as admitting or imply that in any form this information structure has been the general skill in this areaThe prior art that art personnel are known.
Utility model content
The purpose of this utility model is to provide a kind of speed probe assembly of engine, connects thereby overcomeThere is lacking of interfering in the belt of the belt pulley of sending and receiving motivation front damper and harvester and speed probe supportFall into.
For achieving the above object, the utility model provides a kind of speed probe assembly of engine, turnsSpeed sensor cluster comprises: support, support comprises connecting portion and the installation portion that horizontal direction arranges, and connectsPortion is fixed on the gear chamber cover of engine, and connecting portion is directly over the front damper of engine,Between the line at the top dead centre Yu Qi center of front damper and vertical plane, there is the first angle; Installation portion is provided withSpeed probe installed surface, speed probe installed surface is provided with installing hole, the axis of installing hole and rotating speedInstallation of sensors face is vertical, has the second angle, the first angle etc. between the axis of installing hole and vertical planeIn the second angle; Speed probe, speed probe is arranged in installing hole, and the spy of speed probeThe just top dead centre to front damper of head.
Preferably, in technique scheme, the first angle and the second angle are 29.9 ° to 30.1 °.
Preferably, in technique scheme, the first angle and the second angle are 30 °.
Compared with prior art, the utlity model has following beneficial effect:
Speed probe is between front damper and the belt pulley of harvester, and such structure passes rotating speedThe contact-making surface of belt and front damper has been avoided in the installation site of sensor, can avoid support and sensor and skinThe interference of band.
Brief description of the drawings
Fig. 1 is the structure chart according to support of the present utility model.
Main description of reference numerals:
1-support, 11-speed probe installed surface, 12-installing hole, 13-bolt hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail, but should managesSeparate protection domain of the present utility model and be not subject to the restriction of detailed description of the invention.
Unless separately have other clearly to represent, otherwise in whole description and claims, term " comprised "Or its conversion element or the part of stating being understood to include as " comprising " or " including " etc.,And do not get rid of other element or other part.
Be arranged on engine according to the speed probe assembly of the engine of the utility model detailed description of the inventionGear chamber cover on, it comprises support 1 (as shown in Figure 1) and speed probe.
As shown in Figure 1, support 1 comprises connecting portion and installation portion, and connecting portion is provided with two bolts hole 13,For being connected with the gear chamber cover of engine. Installation portion is provided with speed probe installed surface 11, revolution speed sensingAngle between device installed surface 11 and horizontal plane is the second angle α. Speed probe installed surface 11 is provided withInstalling hole 12, the axis of installing hole 12 is vertical with speed probe installed surface 11, the axle of installing hole 12Angle between line and vertical plane (i.e. 0 direction) is the second angle α. Speed probe is arranged on peaceIn dress hole 12, the lower end of speed probe is provided with probe.
Support 1 is arranged on the top of the front damper of engine, and connecting portion is in the front damper of engineDirectly over, installation position is in the oblique upper of front damper, the company at the top dead centre Yu Qi center of front damperAngle between line and vertical plane (i.e. 0 direction) is the first angle, and the first angle equals the second angleα. Therefore the probe of this top dead centre and speed probe is just right, guarantees that speed probe can be known before getting to subtractThe tach signal of shake device.
Preferably, the first angle and the second angle are 29.9 ° to 30.1 °. Preferably, the first angle and secondAngle is 30 °.
Speed probe is between front damper and the belt pulley of harvester, and such structure passes rotating speedThe contact-making surface of belt and front damper has been avoided in the installation site of sensor, can avoid support and sensor and skinThe interference of band.
The aforementioned description to concrete exemplary of the present utility model is in order to illustrate and the order of illustration. These descriptions not want the utility model to be defined as disclosed precise forms, and obviously,According to above-mentioned instruction, can much change and change. Exemplary embodiment is selected and describedObject be to explain certain principles of the present utility model and practical application thereof, thereby make the skill of this areaArt personnel can realize and utilize various exemplary of the present utility model and variousSame selection and change. Scope of the present utility model is intended to be limited by claims and equivalents thereof.
