The double central frame beam crossbeam of doing transmission shaft center support support
Technical field
The utility model relates to the Manufacturing Technology for Automotive Parts field, particularly a kind of double central frame beam crossbeam of doing transmission shaft center support support.
Background technology
The goods carrying vehicle of extension shaft distance is because transmission shaft is long, and the natural frequency of vibration reduces, and is prone to produce resonance, needs transmission shaft is divided into two sections and add center support, and therefore a support must be installed on vehicle frame is used for the supporting drive shaft center support.And near this support because the needs of body frame structure for automotive intensity need to connect an intermediate transverse girder.Owing near the same position of vehicle frame, disposed two parts, thereby caused the waste of material and the increase of quality, be unfavorable for the manufacturing cost and its usage economy of automobile.
Summary of the invention
The utility model proposes a kind of double central frame beam crossbeam of doing transmission shaft center support support, and it can overcome the problems referred to above.
This double central frame beam crossbeam of doing transmission shaft center support support that the utility model provides; Strike out the channel-section rail of unequal section with steel plate; Its left end upper and lower faces is connected with three rivets with upper and lower each connecting panel small end respectively, and the big end of two connecting panels is connected with four rivets with longeron upper and lower aerofoil in a vehicle frame left side is inboard respectively; In like manner its right-hand member upper and lower faces is connected with three rivets with upper and lower each connecting panel small end respectively, and the big end of two connecting panels is connected with four rivets with the upper and lower aerofoil of vehicle frame right vertical beam is inboard respectively, to guarantee enough Joint strenghts.The front end face middle part leans on the place, two ends to dash has two underloading circular holes, and the front end face two ends dash respectively has underloading half slotted hole, and under the prerequisite that guarantees sufficient intensity, its quality is less; Half slotted hole that while front end face two ends are dashed, it is inboard to guarantee that parts such as car electrics wire harness and brake pipe pass and be installed in the left and right longeron of vehicle frame smoothly, for these parts provide an installation environment preferably.The middle part, lower surface is to the installation dimension requirement of fovea superior with the assurance transmission shaft; And recessed part makes progress in the middle part of the lower surface; Its lower surface backward tilts at an angle to guarantee the attachment face and the transmission shafts line parallel of transmission shaft center support, guarantees the designing requirement that transmission shaft is arranged.The left and right both sides of transmission shaft center support are connected middle part, central frame beam crossbeam lower surface with bolt, packing ring, spring washer and nut respectively, to guarantee the bonded assembly reliability.This double central frame beam crossbeam of doing transmission shaft center support support has played the effect of transmission shaft center support support and central frame beam crossbeam simultaneously, can reduce production costs, and help the car opertion economy, can be widely used in goods carrying vehicle.

Each label is in Fig. 1~4: 1-vehicle frame left side longeron, 2-connecting panel, 3-central frame beam crossbeam, 4-rivet, 5-vehicle frame right vertical beam, 6-M14 * 40 bolts, 7-φ 14 packing rings, 8-φ 14 spring washers, 9-M14 nut, 10-transmission shaft center support.
The specific embodiment
Be elaborated below in conjunction with accompanying drawing.
Shown in Fig. 1~4, the installation matrix of central frame beam crossbeam is vehicle frame left side longeron 1 and vehicle frame right vertical beam 5, and the supporting of central frame beam crossbeam is represented with long and two-short dash line liking transmission shaft center support 10, does transparence and handles.Central frame beam crossbeam 3 usefulness steel plates strike out the channel-section rail of unequal section; The left end upper and lower faces of central frame beam crossbeam 3 is connected with rivet 4 with upper and lower each connecting panel 2 small end respectively, and two connecting panels, 2 big ends are connected with rivet 4 with vehicle frame left side longeron 1 upper and lower aerofoil is inboard respectively; In like manner the right-hand member upper and lower faces of central frame beam crossbeam 3 is connected with rivet 4 with upper and lower each connecting panel 2 small end respectively, and two connecting panels, 2 big ends are connected with rivet 4 with vehicle frame right vertical beam 5 upper and lower aerofoils are inboard respectively, to guarantee enough Joint strenghts.Central frame beam crossbeam 3 front end faces middle part leans on the place, two ends to dash has two underloading circular holes, and the front end face two ends dash respectively has underloading half slotted hole, and under the prerequisite that guarantees sufficient intensity, its quality is less; Half slotted hole that while front end face two ends are dashed can guarantee that parts such as car electrics wire harness and brake pipe pass and be installed in vehicle frame left side longeron 1, vehicle frame right vertical beam 5 inboards smoothly, for these parts provide an installation environment preferably.Middle part, central frame beam crossbeam 3 lower surfaces is to the installation dimension requirement of fovea superior with the assurance transmission shaft; And recessed part makes progress in the middle part of the lower surface; Its lower surface backward tilts at an angle to guarantee the mounting plane and the transmission shafts line parallel of transmission shaft center support 10, guarantees the designing requirement that transmission shaft is arranged.Transmission shaft center support 10 left and right both sides use M14 * 40 bolt 6, φ 14 packing rings 7, φ 14 spring washers 8 and M14 nut 9 to be connected middle part, central frame beam crossbeam 3 lower surfaces respectively, guaranteeing the bonded assembly reliability, and remove and install conveniently.This double central frame beam crossbeam of doing transmission shaft center support support has played the effect of transmission shaft center support support and central frame beam crossbeam simultaneously, can reduce production costs, and help the car opertion economy, can be widely used in goods carrying vehicle.
As shown in Figure 2, connecting panel 2 usefulness steel plates are processed rectangle and trapezoidal fabricate block, and the promptly big end of rectangular end is that small end has dashed three rivet mounting holes towards four rivet mounting holes, trapezoidal end are arranged.Transmission shaft center support 10 is installed in central frame beam crossbeam 3 midway location bottoms.
As shown in Figure 3; Middle part, central frame beam crossbeam 3 lower surfaces is to the installation dimension requirement of fovea superior with the assurance transmission shaft; And recessed part makes progress in the middle part of the lower surface; Its lower surface backward tilts at an angle to guarantee the mounting plane and the transmission shafts line parallel of transmission shaft center support 10, guarantees the designing requirement that transmission shaft is arranged.
As shown in Figure 4, central frame beam crossbeam 3 usefulness steel plates strike out channel-section rail.
